Looking at a 2001 Outback LS with 315 hours. How many hours of life is typical, prior to major overhaul on the Chevy Indmar engine? Is 315 a lot in a boat application?

I average 50 -60 hours a year.. If the motor has been serviced properly (fluid changes, etc.) you should have MANY hours left. I have seen 1 year old boats for sale from ski/wakeboard camps with 500-600 hrs on them.
Since an inboard runs at higher rpms than a vehicle, if you considered those hours as miles... say, 75 mph for a higher rpm, that would be 23,000 miles... My tahoe has 102k miles in 3 years and runs like a top..
Since boats only get used 3-6 months a year by most, you don't hear of many that get very high... Considering my 06 has 157hrs, I would not worry about an 01 with 315 hrs. You might want to have a mechanic look it over to ensure it is in proper order... I would think that if you changed plugs, wires and fluids, it should last MANY more hours...

I agree. All things considered, it is a GM marine engine. I have a GM Diesel truck with 1180 hrs in 3 years (48000 miles) which works out to about 40 miles per hour. I guess I drive alot slower!

I have a 98 with around 600hrs. Just check the compression to make sure everything is within a few of each other.

I had a 1979 Glastron Carlson until 2002 and I sold it to a friend and it is still running without a rebuilt. 98outback, do you have the PCM engine? I can't remember when they changed over.

1,000 hrs-no big deal with normal maintence
2-3,000 hrs very possible with good-great servicing.

salt water---changes everthing, but still possilbe with finatical servicing

It will depend on proper maintenance and how the motor is used (i.e. wakeboard speed vs. barefoot speed). You could expect at least 800 hrs as worst case. I have been on ski teams with boats having over 1200 hrs with no problems (and still good compression).

1500 - 2000 hrs shouldn't be a prob. Just do regular maintanence. You might have to change the water pump, starter, raw water pump, etc eventually because that kind of stuff even wears out on an auto.

hope this helps

I got to chime in here... the GM 5.7/350 is practically a bullet proof motor.
I'm running two vehichles now pushing 250,000 miles with the 5.7 eng. My '98 mobius has well over 700 hrs, and runs great, a buddy of mine is pushing 3000 hrs and is running good. CHANGE OIL regular, watch heat guage, and lay off upper RPM range for long periods of time and she will serve you a long time ! Heck you can get a brand new 5.7 marine eng.carb to oil pan for bout $3500 from Michigan Motorz on ebay. compare that to a V-6 outboard price :wink:

Thanks to all for the great information. Being new to the inboard arena, I didn't have much insight into to it. I spoke with what now appears to be an uneducated newbie salesman, who said "315 hours thats a lot", and then proceeded to show me the new $48K Moomba sitting in his showroom. I have seen a lot of inboards listed with 900 or so hours, so this reaffirms my initial thoughts. Thanks again!

I'm not an engine expert but I think that 315 hours is probably about right for a 2001. Certainly not high hours, but it hasn't sat in a garage unused for years at a time either.

I bought a used 2001 Outback LS last fall. I've been very happy with it. With a 7 or 8 year old boat, though, condition is everything.

315 is barely broke in. Stay on top of your maintenance and you will get plenty more as everyone else has said.

Interesting your 98 Mobius is an Indmar and mine is the PCM. They must have been an option to pick from. I was told when I bought my boat in 2002 to stay away from the Mercuiser direct drives. I think these engines will last longer then most people keep their boats.
